SPECIFICATION forming part of Letters Patent No. 428,559, dated May20,1890. Application letl January 14,1890. Serial No. 336,875. (Nomodel.)

T0 aZZ wt0m it may concern.-

Be it known that I, VILLIAM J. GOHN, of

Oakwood, in the county of Vermilion and State of Il1inois,have inventedcertain newand useful Improvements in Corn- C ultivators; an d I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to vmake and use the same.

My invention relates to an improvement in tongueless cultivators, theobject of the same beig to provide the same with an adjustable arc Afurther object is to provide a combination box and axle, whereby freeupward, downward, and side movements may be effected.

A further object is to provide means for governing the depth and angleof the shovels. p

With these ends in view my invention con-- sists in the certain featuresof construction and combinations of parts, as will be hereinafter fullydescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan v iew of theelevator. Fig. 2 is a section thereof on lines :c a: of Fig. l. Fig. 3is a cross-section on line y y of Fig. l. Fig. 4 is a view thereof online .ez of Fig. l. Figs. 5 and G are views of the clevis and coupling.Fig. 7 is a view of the wheel-guide, and Fig. 8 is a view of theshovel-clamp. Fig. 9 is a section online w w of Fig. 3.

A represents a vertical rod, having its upper end mounted in the yoke B,as shown at b. The yoke is provided with the collars b', adapted toreceive suitable bolts, by means of which the same are compressed on thebar C, and by means of which the same may be adjusted. The yoke isprovidednear its ends with the notches b2 to receive the upper ends ofthe brace-rods D, the lower ends of said rods being screw-threaded andentering perforations formed in the iiange of the swivel E.' The rod Apasses through the center of the swivel E.

By the employment of the yoke B, rods D, and swivel it will be seen'that the machine may be adjusted vertically and through the swivels havea slight lateral movement, thereby relieving the parts from strain. ThecouplingF is secured to the beams G, andthe rod A passes through theperforations formed in the free ends of its arms f.

G represents the axle and coupling device combined, the same beingadapted to iit snugly between the arms f, and is provided with theenlarged recess g in its forward part to receive the clevis H, which isof ordinary construction. It will be observed that the rod A passesthrough the parts E, F, and G, thereby holding the same in position. Thepart G on its axle receives the wheel D, adjoining which is journaledone side of the wheel-guide J, the opposite side being journaled on theinner end of the axle. The draftbar K is secured to the clevis andpasses through a perforation formed in the end of the guide J. Aspring-key e passes through rod A just above swivel E to hold the samein position. The spring-key e also passes through the clevis H toprevent the arch from being withdrawn. The beams G are attached at theirrear ends to the shanks M by means of the clamps m. The arch N is alsosecured to the shanks M bymeans of suitable adjustable clamp n. Theshanks are provided with the lug n', adapted to receive the brace 0. Theshovels p are pivoted to the shanks M, as shown at o', and are rigidlysecured to the braces o at their lower ends. The braces are adjustablein the lugs n', as the same are screw-threaded and provided with nuts on each side thereof.

The rear upper arch (shown in Fig. 1) and the upper arch (shown in Fig.4) are not i11- cluded in this invention, the same having been used byway of illustration. j

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is

l. In a cultivator, the combination, with the bar C, the rod A, and yokeB, adjustably secured to said bar, of adjustable rods secured to theyoke and swivel E, substantially as set forth.

2. In a cultivator, the combination, with the coupling F,secured to thebeam G', the

axle and coupling device being provided with specification in thepresence of two subscribthe recess g t0 receive the clevis, 0f aerossing' Witnesses.

bmadjustably connected with the rod A [T v T and yoke B, the rod Aengaging the coup- Xx ILLAM J' GOID" 5 iings F and G, substantially asshown and de- XVituesses:
